Diego Maradona has revealed he advised his son-in-law Sergio Aguero to move to City.

The legendary Argentinian – considered by many to be the greatest player the world has ever seen – gave his blessing to the £38m deal which saw Aguero move to the Blues.

Real Madrid had also been in hot pursuit, along with Juventus, but Maradona told Aguero, nicknamed Kun, a move to City would be a good one. Now he is backing Aguero and his Blue team-mates to push hard for Premier League and Champions League honours.

“People at Atletico Madrid said I was a fool,” said Maradona, whose youngest daughter Giannina is married to the explosive City striker.

“I told them that this foolish person is not that much of a fool, because Aguero is playing in a team at Manchester City where he is going to fight for everything.

“It was not fair, with respect to his team-mates at Atletico Madrid, for Aguero to be playing for a team who were not competing for the big championships.

“It was worrying me that he may have played for many years for Atletico Madrid and for that time they would only have one star, and didn’t do much in Europe.

“Now Kun Aguero is playing at a place he deserves.”

Aguero is in line for his first European game for the Blues tomorrow after an explosive start to his career, Saturday’s hat-trick against Wigan taking his tally to six goals in four appearances.

Maradona’s blessing comes just before City take on Napoli, where the Argentinian legend achieved God-like status by leading them to two Serie A titles and a Uefa Cup in the late 1980s.

But Maradona cannot be at the Etihad Stadium for the game, as he is preparing his new United Arab Emirates club Al Wasl for an Etisalat Cup tie, ironically against Sheikh Mansour’s other club, Al Jazira.
